Question 5 Which of the following would have a significant impact on the maximum force of friction between the bottom of a person's shoe and the floor? (Assume that the floor is one solid piece and that it is dry.) Pick all correct answers - there is more than one. Your answer: O the length and width of the shoe the material that the bottom of the shoe O the weight of the person wearing the shoe what floor the person is on (1* floor or 2nd floor, not the material the floor is made of)

Question 2 2.0 m Pivot 70° Air A 0.550 kg wooden block is spun around on a wooden table. The wooden block is being spun around on a 2.00 m long massless wire. The wooden block has air being pushed out behind it causing a thrust force of 3.20 N. The air is being pushed out at 70.0" from the radial line as shown in the figure. If the block is initially at rest and the coefficient of friction is 0.300, what is the tension in the wire after 20.0 revolutions?

Review A sailboat can be propelled into the wind by a maneuver called beating to windward. Beating requires the sailboat to travel in a zigzag pattern at an angle to the wind that is greater than the no-go zone, which is shaded red in (Figure 1). When a sailboat is just outside the no-go zone (boats B in the figure) the wind Part A exerts a force F on the sail that has a component in the direction of motion v. Similar comments apply to boats C. The work done by the wind on the sail is W = Fdcose, and because v = d/t, the propulsion power P = W/t delivered to the sailboat is Fvcose, where 0 is the angle between the sail force and the Assuming that F and v have the same magnitudes for each sailboat, will the propulsion power delivered to sailboats B be greater than, less than, or the same as the propulsion power delivered to sailboats C? direction of motion. O Less than Figure 1 of 1 O Greater than O Equal to Wind direction Submit Request Answer Part B If F = 900 N and v = 15 m/s, what…

QUESTION 12 Two boxes (M1-1 kg. M2-2 kg) are adjacent to each other horizontally (NOT vertically stacked) on a frictionless floor, with Mi to the left of M2. A horizontal force of 12 N pushes on M1 towards the right a horizontal force of 18 N pushes on M2 towards the left. What is the magnitude of the force of M1 on M2? 12 N O 18 N O 14 N 2 N O NOTA
